Hana kānana- loiloi ʻia ka kānana no ke ana ʻana i ka hoʻemi ʻana o ka nui o nā aerosol kikoʻī i ka ea e hele ana i ka kānana.
Agena hoao- ka aerosol i hana ʻia i ka wā o ka hoʻāʻo hana kānana.
Ka nui o ka leaka i loko (TIL)- ka nui o ka aerosol kiko'ī e komo ana i loko o ka ʻaoʻao o ka respirator i hoʻāʻo ʻia ma o ke komo ʻana i ka kānana a me ka leaka ʻana o ka maka, ʻoiai e hana ana ka mea hoʻohana i nā ʻano hana i loko o kahi keʻena hoʻāʻo.
Leaka loko (IL)- ka nui o kahi aerosol kikoʻī e komo i ka maka o ka respirator i hoʻāʻo ʻia, ʻoiai ka mea hoʻohana e hana i ka hanu maʻamau no 3 mau minuke i loko o kahi keʻena hoʻāʻo.ʻO ka nui aerosol hoʻāʻo (helu median diameter) ma kahi o 0.5 micro mika.
Haʻule kaomi- ua hoʻokuʻu ʻia ka ea kū'ē i kona neʻe ʻana ma waena o kahi mea, e like me kahi kānana respirator.
Ma muli o ka papa ma luna, he mea kūpono ke noʻonoʻo ʻia ʻo Kina KN95, AS/NZ P2, Korea 1st Class, a me Iapana DS FFRs ma ke ʻano he "like" me US NIOSH N95 a me ʻEulopa FFP2 respirators, no ka kānana ʻana i nā mea i hoʻopaʻa ʻia i ka aila e like me nā hopena. mai nā ahi ahi, PM 2.5 haumia ea, lua pele, a i ʻole bioaerosols (e laʻa i nā maʻi virus).Eia nō naʻe, ma mua o ke koho ʻana i kahi respirator, pono nā mea hoʻohana e nīnau i nā lula a me nā koi no ka pale ʻana i ka hanu kūloko a i ʻole e nānā me ko lākou mau luna olakino olakino no ke alakaʻi koho.
